npx cap add @capacitor-community/electron fails if there's a space in the path.

**Describe the bug**
Running `npx cap add @capacitor-community/electron` fails if there's a space anywhere in the path name.

Error thrown for dir `/Users/person/path-with space`:
```bash
Adding Electron platform:
node:internal/process/promises:392
new UnhandledPromiseRejection(reason);
^

UnhandledPromiseRejection: This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason "/bin/sh: line 0: cd: /Users/person/path-with : No such file or directory
```

**To Reproduce**
Steps to reproduce the behavior:

1. Make a folder with a space somewhere in the path.
2. Follow the official [getting started](https://capacitor-community.github.io/electron/docs/gettingstarted) steps.
2. Run step 3: `npx cap add @capacitor-community/electron`
3. See the error.

**Expected behavior**
Commands should properly escape spaces and other special characters in paths, and run without errors.

**Desktop (please complete the following information):**

- OS: MacOS 15.5
